Improving the extragalactic distance scale using Cepheids in M33
… The first study uses Cepheids in two areas of M33; a sample from the metal-rich central region is compared with the more metal-poor sample from the southern spiral arm. Period-luminosity relations in the reddening-free Wesenheit index Wvi are constructed for the two samples and the measured …

THE CEPHEIDS OF M33: DISTANCE AND METALLICITY EFFECTS THROUGH SLOAN FILTERS
… 1.3 million stars in the nearby spiral galaxy M33. Over 1500 Cepheids were identified and Leavitt Laws were empirically derived. The slopes were found to be consistent with semi-empirical determinations. By adopting the semi-empirical slopes, a mean distance modulus of 24.57 ± 0.06 mag to the …

Point Process Modelling of Objects in the Star Formation Complexes of the M33 Galaxy
… objects in the star formation complexes of the M33 galaxy. The GPP models circumvent the limitations of the two-point correlation function employed in the current astronomy literature by naturally accounting for the inhomogeneous distribution of these objects. The spatial distribution of these …

Accreting Compact Objects in Technicolor: Multiwavelength Characterization of High Mass X-ray Binaries in the Local Group
… resolved recent star formation history (SFH) of M33. In M31, I used observations from the Hubble Space Telescope (HST), the Chandra X-ray Observatory, and the Nuclear Spectroscopic Telescope Array (NuSTAR) to characterize the population of HMXBs in that galaxy and measure the overall HMXB …

… the simulation of star formation history in the M33 galaxy. Based on the detailed analysis of the M33 galaxy evolution, we showed that, in order to resolve the evolution parameter degeneracy problem, it is necessary to use 2-D capabilities of the model as well as synthetic colour-magnitude …

The accuracy of integrated star clusters parameters. The effects of stochasticity /
… from literature. For 747 star clusters in the M33 galaxy, available optical data have been supplemented with our near-infrared data measured on 2MASS images, and their age, mass, and extinction have been derived. A typical disruption time of star clusters in the M33 galaxy is found to ~300 Myr, …

Neutral hydrogen observations of spiral and irregular galaxies
… two nearby galaxies af late spiral type, namely M33 and NGC 2403. The severe warping of the HI layer in the outer parts of M33 was clearly seen, and the origin of this phenomenon is discussed. Sensitive low-resolution maps reveal only a very slight warp in NGC 2403, while maps at the full …

Engineering human single-chain T cell receptors
… murine T cells. The high affinity scTv, called m33, that is specific for the pepMHC SIY/Kb was used to redirect T cells with similar antigen sensitivity to the full-length m33 TCR. An inherent problem with full-length TCR gene therapy is the generation of receptors of unknown specificity through …

Chemodynamical Properties of Simulated Late-type Galaxies

Ecologie des stades larvaires et juvéniles du crabe tourteau (Cancer irrotatus Say, 11817), dans le détroit de Northumberland, Canada
Le but de l’étude est de décrire les facteurs qui peuvent influencer le recrutement au fond du crabe tourteau, et de déterminer la relation entre la dynamique de population des larves et celle des juvéniles. Les aspects étudiés sont : l’abondance relative des différents stades larvaires, …
